Justin Bieber fan attacks Kurt Cobain on Twitter

One hardcore Belieber has sparked a war on Twitter after claiming that Justin Bieber is "much bigger" than late Nirvana frontman Kurt Cobain.

Twitter user "Amanda Bieber" caused outrage when she compared the popularity of the pop teen to the late grunge singer, suggesting that Justin could be Kurt reincarnate.

"Kurt Cobain (some rock singer) died in 1994, the same year Justin Bieber was born. RT if you think Bieber is Kurt reincarnated," Amanda wrote on her twitter.

Justin was born on March 1 1994, Kurt died on April 5 1994, so that theory doesn't quite add up.

The response on Twitter was less than positive, and "Mrs. Bieber" soon became defensive.

"Justin Bieber is much bigger than Kurt Cobain, so shut up," she fired back at haters. "Did Kurt Cobain have the biggest fanbase on Twitter? No." Mainly because Kurt Cobain died more than a decade before Twitter was invented, but mathematics doesn’t seem to be this kid's strong suit.Her comment was retweeted over 5,000 times and also went viral through Facebook.

"Kurt Cobain is trending because of my tweets about how Bieber is much better than him. I made you relevant Kurt, you owe me!" she responded after Kurt Cobain became a trending topic on Twitter.

She's tweeting to a dead person.

It seems Kurt isn't just the only musician to be at the mercy of "Mrs. Bieber". She's also compared her idol to Michael Jackson, Lady Gaga and even Freddie Mercury.

"LOL at people saying Freddie Mercury was a great role model and Bieber is not. You know Freddie was gay and had AIDS right?"

Of all the negativity that is surrounding the young tweeter, she does have one tender message for her fantasy husband.
